-6 claims.

My invention relates to improvements in electrical connectors and more particularly to plugs of the appliance type which must be .inserted into a closely fitting guard surrounding the plug jacks with which the plug is to be engaged.

One of -the principal objects of my invention is to provide a plug of the above described character so constructed and arranged whereby the same may be readily and economically manufactured and assembled and which may be conveniently and quickly attached to electrical feed wires which are commonly of the flexible cord type.

Another object of my invention is to provide a connector construction which may be of a neat and attractive appearance and design without sacrifice of ruggedness, durability, eiiiciency, facility of use, or facility of wiring preparatory to use.

A further object of my invention is to provide a connector of the above described character equipped with means for facilitating removal of the connector from the plug jacks.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawing.

Referring to the drawing wherein like reference characters designate like parts throughout the several views:

Figure 1 is a side elevation of my invention.

Figure 2 is a longitudinal section therethrough.

Figure 3 is a top plan View thereof.

Figures 4 and 5 are detail sectional views taken on the lines 4-4 and 5-5 respectively of Figure 1.

Figure 6 is a perspective view of the shroud.

In practicing my invention, as illustrated in the drawing, I provide a pair of molded insulating casing sections l and II of identical form and dimensions. The members or sections I I) and I I are fashioned with flat inner faces which are normally adapted to lie against each other throughout the length thereof as clearly illustrated in Figures 4 and 5 of the drawing. Said inner faces are complementally recessed as at I2 to accommodate a pair of combined socket contact and wire terminal units I3, the latter being of the split socket type and provided at one end with binding screws I4 effecting connection with feed wires I5. The binding screws I4 are threaded within sockets formed in the section II whereby to secure said units I3 fixed thereto as clearly illustrated in Figure 4 of the drawing.

The jack engaging end of the sections I0 and I'I are formed with opposed pairs of apertures .I6 defining 'openings communicating With thev recesses I2 and through Ywhich the plug jacks of an applianceare received for insertion Within the socket contactends of the units I3. The opposite 'ends of the sections Il] and II receive thereon a bonnet I1 through which the Wires i5 extend and Which bonnet encloses and protects the binding screws I4. One end of vthe bonnet -is interiorly recessed to dene a seat I8 accommodating the upper ends of the'sections I0 and II. The sides of the bonnet are formed with laterally disposed arcuate-shaped bosses I8 over which are extended the upper ends of bails I9, the lower ends being pivotally connected to the upper section of a shroud 20 embracing the sections II) and I'I and securing the same in connected relation to form a unitary connector casing. The oppositely disposed ends of the shroud 20 are slotted an appreciable distance towards the top to permit expansion in the lower section thereof. The upper faces of the bosses I8 at the jointure with the body proper of the bonnet I 'I are recessed to provide seats 2| for receiving the upper ends of the bails I9 as clearly illustrated in Figures 1 and 2 whereby to preclude accidental displacement of the upper ends of the bails outwardly over said bosses. v

From the foregoing it will be apparent that by displacing the upper ends of the bails I9 outwardly over the bosses I8 the shroud may be lowered and detached from the sections I0 and II and thus permit the bonnet I'I and the sections to be disassembled with respect to each other for connecting or disconnecting the wires I5 to the units I3. A reverse operation serves to effect assembling of the device and it is to be noted that the bosses I8 also constitute nger pieces whereby the device may be readily connected and disconnected from the plug jacks of an appliance.

It will be apparent, from the foregoing, that I have provided a simple and eicient connector or plug which may be readily disassembled for connecting the feed wires thereto and at the same time may be conveniently attached or detached from the appliance.

It is obvious that the invention is not conned to the herein described use therefor as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles of operation,

ing said shroud to said bonnet for maintainingthe latter and said sections in connected relation.n

2. A device of the character described, com" prising, a casing having a Vpair of `separable sections, a bonnet tting said casing andprovidedf with outwardly extending end portions, a shroud surrounding said sections for securing the latter in connected relation, and bails detachably connecting said shroud to said portions for maintaining said bonnet and said sections in connected relation.

3. A device of the character described, comprising a casing having a pair of separable sections, a bonnet resting upon the upper ends of the sections and extending around the side Walls thereof, a shroud surrounding said sections and securing the same in their proper engaged position, and bails pivotally carried by the shroud and extending over the bonnet for maintaining the same and the sections in their assembled position.

4. A device of the character described, cornprising a casing having a pair of separable sections with tapering outer walls, a bonnet resting on the upper ends of the sections, a tapering shroud surrounding said sections, and bails pivoted to the shroud and adaptedV to swing upwardly over the edges of the bonnet for maintaining the same and said sections in their assembled position.

5. A device of the character described, comprising a casing having a pair of separable sections, a bonnet fitting over said sections, a shroud removably surrounding the lower ends of the sections and having a limited upward movement, and

bails pivotally carried by the shroud and adapted to swing over the bonnet for maintaining the same and the sections in their assembled position.

6. A device of the character described comprising a casing having a pair of separable sections, abonnet fitting over said sections, ears carried by the ends of said bonnet, a shroud removably surrounding the lower ends of the sections and having a limited upward movement thereon, and bails pivotally carried by the shroud and adapted to swing upwardly at an angle over the ears on the bonnet for maintaining the same on the sections and holding the sections within the bonnet.
